Abstract

Cross-luminance and cross-color artifacts can be eliminated if in an extended encoder the chrominance information is made pairwise equal at two time instants and the luminance information (i.e. the high horizontal frequencies) is also made equal at these two time instants. In an extended decoder, the high-frequency luminance information can be separated again from the modulated chrominance information by, for example, (i) subtracting the information of the pairs at the above-mentioned time instants and by dividing them by 2 (this yields chrominance), and by (ii) averaging the information of the pairs at these time instants (this yields high-frequency luminance).
